Abstract
The invention relates to a cutter device of a grass trimmer. The cutter device comprises a cutter rack connected with a driving shaft of a driving device and blades arranged on the cutter rack, wherein the cutter rack adopts a circular structure with mounting frames, and the number of the mounting frames is the same as blades; a mounting hole allowing the driving shaft to penetrate through is formed in the middle of the cutter rack; the mounting frames consist of upper pressing sheets and lower pressing sheets, and one ends of the upper pressing sheets are not connected with one ends of the lower pressing sheets; at least one fastening hole allowing a fastening bolt to penetrate through is formed in opposite positions of each upper pressing sheet and each lower pressing sheet; holes are formed in one ends of the blades; the perforated ends of the blades are inserted between the upper pressing sheets and the lower pressing sheets and are fastened through the fastening bolts.
Description
Technical field
The invention belongs to mower field, refer to especially a kind of cutter for mower device.
Background technology
The mower now using, cutter arrangement is the machine-processed essential elements of mowing.The cutter arrangement that is now used in mower is the structure that all blades are fixed on one, then cutter arrangement is installed on the driving shaft of mower.
There is following defect in the cutter structure now using, when damaging appears in one of them blade, just must change whole cutter arrangement, causes so a kind of waste.And need to pull down driving shaft fastening bolt, and because cutter arrangement is the attrition component in mower, need to often change, dismounting repeatedly also can cause driving shaft with becoming flexible between cutter arrangement, produces power loss.
On the other hand, existing cutter arrangement all not metal process, it is large that gross weight is wanted, and the in the situation that of identical driving power, affect the cutting effect of mower.
Summary of the invention
The object of the invention is that existing cutter arrangement is proposed to one and improve technical scheme, by the technical program, can realize when the allowing blade replacement more, do not need to dismantle driving shaft bolt, and only need to change the blade of damage, do not need to change whole cutter arrangement, and can reduce the weight of cutter arrangement, improve the service efficiency of drive unit.
The present invention is achieved by the following technical solutions:
A device, includes the toolframe connecting for the driving shaft of same drive unit and is installed on the blade on toolframe; Described toolframe is the circular configuration with the identical installing rack of same knife number, is provided with for the installing hole through driving shaft in the middle of it; Upper compressing tablet and lower sheeting that described installing rack is not connected by one end form, and the position that upper compressing tablet is relative with lower sheeting is provided with at least one fastener hole, for passing fastening bolt; One end of blade arranges porose, will have nose end to be inserted between compressing tablet and lower sheeting and use fastening bolt fastening.
Installing rack is structure as a whole with toolframe, and the quantity of described installing rack is three and also waits radian to be arranged on the circumference of toolframe.
Described toolframe is that plastics, light metal, iron or ferroalloy etc. are made.
The present invention's beneficial effect is compared with the existing technology:
Toolframe in cutter arrangement of the present invention no longer needs dismounting after being installed on driving shaft, when blade occur to damage, by installing rack and on fastening bolt be the blade of replaceable damage and do not need to change whole device.
Accompanying drawing explanation
Fig. 1 is cutter arrangement structural representation of the present invention.
Embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
As shown in Figure 1, a kind of cutter for mower device, includes the toolframe 11 connecting for the driving shaft of same drive unit and is installed on the blade 13 on toolframe; Described toolframe is that plastics, light metal, iron or ferroalloy etc. are made; What select in the present embodiment is to be formed by plastic processing, can select in other embodiments light metal, iron or ferroalloy etc. to make toolframe, from the viewpoint of raising the efficiency, and preferred plastics or light metal.The blade shapes of the structure co-occurrence cutter arrangement front end of described blade is identical, only in rear end, is provided with for the fixing hole of same installing rack or similar device;
Described toolframe 11 is that installing rack is structure as a whole with toolframe with the circular configuration of the identical installing rack 12 of same knife number, and the quantity of described installing rack is three and also waits radian to be arranged on the circumference of toolframe;
In the middle of toolframe, be provided with for the installing hole through driving shaft; Upper compressing tablet and lower sheeting that described installing rack is not connected by one end form, and the position that upper compressing tablet is relative with lower sheeting is provided with at least one fastener hole, for passing fastening bolt; One end of blade arranges porose, will have nose end to be inserted between compressing tablet and lower sheeting and use fastening bolt fastening.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
